Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    “The complete life, the perfect pattern, includes old age as well as youth and maturity. The beauty of the morning and the radiance of noon are good, but it would be a very silly person who drew the curtains and turned on the light in order to shut out the tranquillity of the evening. Old age has its pleasures, which, though different, are not less than the pleasures of youth.”
    —W. Somerset Maugham (1874–1965)

    “Our courage breaks like an old tree in a black wind and dies,
    But we have hidden in our hearts the flame out of the eyes
    Of Cathleen, the daughter of Houlihan.”
    —William Butler Yeats (1865–1939)
